How closely do you think that the ride mechanism and/or vehicle are connected to the ride itself? When Indy opened in '95, it was a completely unique and new kind of ride vehicle (as numerous signs in the queue point out). Now, there are four other rides in the US that use the same concept (Transformers (X 2), Spiderman, and Dinosaur). When I go on any of the other rides I'm always reminded of Indy a little bit. So you think that another completely different ride with the same kind of ride vehicle could exist at Disneyland? One the one hand, plenty of rides use the same kind of vehicles. All of the roller coasters are essentially the same but made to look different (alpine bobsled, space rocket, train). The dark rides use the same kind of track (even Peter Pan, it's just overhead instead of under you). For a time, there was Mansion and Inner Space which are both omnimovers. So it's not unusual to use the same ride mechanism over and over. But other then the omnimover, none of those were unique to Disney. They may have perfected some things, but guests have seen them before at other parks. Disney's unique ride mechanisms are: Omnimover (one in Disneyland, one in DCA), Indy (one in Disneyland, one at Animal Kingdom), and Soarin (one at DCA, one at Epcot). Because these were things invented by Disney and first seen on specific rides, do you think that the ride mechanism itself is too closely tied to the ride to use it in another completely different ride within the same park? For example, the Indy vehicles clearly could be used to create a pretty awesome ride in Tomorrowland. You could theme them to be like a moon rover driving accross the moon, or a vehicle exploring Mars. Even if they made the ride vehicle look totally different so that it didn't remind you of Indy at all, is that mechanism too closely tied with Indy to be used in a different ride?
